Ronaiah Tuiasosopo, the individual behind the hoax that fooled Manti Te'o, has claimed he was the voice of Lennay Kekua during the lengthy phone calls and voicemails exchanged with the Notre Dame All-American.

On Friday, Tuiasosopo backed up his claims by giving Dr. Phil McGraw a sample of his portrayal of Kekua â?? replicating three separate voicemails released during Te'o's interview with Katie Couric on Jan. 24.

McGraw then gave Tuiasosopo's samples to three different laboratories to check it against the voicemails "Kekua" left for Te'o over the course of their relationship.

That Tuiasosopo's voice was a match for the voicemails left on Te'o's phone refutes a report by the New York Post, which wrote that Tuiasosopo's cousin, Tino, served as Kekua on the phone.

Friday's appearance on McGraw's syndicated talk show, Dr. Phil, was the second half of a two-part interview that began Thursday. During the first part of the interview, Tuiasosopo discussed how and why he "killed" Kekua on Sept. 12 and his own "confused" sexual identity.

On Friday, Tuiasosopo gave some of his own background, telling McGraw he was molested as a child.

"I felt that I couldn't do things, accomplish things, pursue things, live out as Ronaiah," Tuiasosopo said to McGraw. "And I felt the need to create this. It has everything to do with what I went through as a child."

He told McGraw that he had been repeatedly molested by a family friend starting when the 22-year-old Tuiasosopo was 12. Tuiasosopo's father, Titus, told McGraw that it was devastating to hear his son detail the alleged abuse.

"When he told me the location, the time, I could go back and vividly remember those trips, the times that these guys came over. That part, right there, was kind of gut wrenching for me."
